OP Trashed the document, lol. For those who still really want to use one of these three, some bits it said: "
For a "low" level pure physical damage build, dex build with sharp infusion is the best choice. It's roughly on par with the Corvian, though Corvian has bleed on self and is a bit heavier. If you do not intend to use a buff, Pontiff Knight Great Scythe is better.
In short: use this one for a dex build with weapon buff (I'd advise to use resins over spells). Otherwise, look into the two others.
Corvian Great Scythe
It has really good scaling for elemental damage. Casters might want to look into it. As usual, it is ill advised to pick an elemental infusion outside of an elemental build. As for luck build, it has a really high bleed (and poison) build up, with an AR not too far behind a dex build for the hollow infusion. However, because of the weapon's low hit rate, bleed isn't really realiable against other players. (thanks to coffeeborne)
In short: maybe the best scythe overall, good for almost every build. You might just want to switch out if you're fighting an oponent using bleed.
Pontiff Knight Great Scythe
It cannot be infused nor buffed, outside of the frost effect you gain with the weapon art. Only dexterity and strength increases AR. Having less than 12 faith won't impact your damage, only the abilty to perform the weapon art.
It's better than the other two for a dex build with no buff. That's it."
Cannot confirm any of that's still up-to-date, though
